A copper sheet of .5 kg drops through a horizontal magnetic field of 1.5 T and it reaches a terminal velocity of 2 m/s. What is the net magnetic force on the sheet after it reaches terminal velocity?
I don't know, you should've studied your textbook or payed attention in class
It need no longer be ferromagnetic. The changing magnetic field will produce an electric powered cutting-edge interior the copper. Feromagnetism is the metallic being extra close to the magnetic field taking over a stable magnetic field.
The net magnetic force after the sheet reaches terminal velocity is exactly the opposite of the force of gravity, i.e. mg 0.5 kg x 9.8 m/s^2 4.9 N, where the positive direction is up. If the magnetic force were smaller (or larger) than mg then the sheet would accelerate downward (or upward).
